ABSTRACT

This invention relates to a set of pieces-connectors to assembly toys in shapes of smooth or grooved cylindrical tubes, smooth or teeth semicircles and the combination of the same. Smooth or toothed tubular semicircles joined to a smooth or grooved cylindrical tube by one of its ends to the middle external portion; smooth or toothed semicircles joined to other smooth or toothed semicircles by its exterior middle portion; cylindrical tubes with a fixed “ring-butt” joined in its middle portion; smooth or toothed semicircles, joined at its two ends by a smooth or grooved cylindrical tube, in its cavity direction, leaving the cavity at sight; cylindrical tubes, joined by their ends forming wheel; smooth or toothed semicircles, joined among them at their middle external portions of their curves perpendicular one to the other; cylindrical tubes folded 90 degrees and reduced in its ends respecting their circumferences. The pieces interact, engaging, fastening, dropping, sliding, grading, stabilizing, turning around and making sound “clicks” among them, constructing and creating an endless 3D shapes, the grooves and the edges-butts will stabilize and grade the development as well as the final result, the combination of smooth pieces with grooved and toothed pieces produce versatile results, having parts with stability and parts with more mobility, subjected to the needs of the different parts of the toy.

OBJECT OF THE INVENTION

The present invention is related to a new model of construction piecesfor 3D-assembly toys totally different from those known until now. Thisnew model is characterized by its novel practical design andimprovements which provide it with a peculiar and unique look.

BACKGROUND OF THE INVENTION

Presently, construction pieces for 3D assembly toys are characterized byits rigidity during the development, and, when the designs are finished,they have no mobility due to their own nature. Examples of them areInterlego, which has registered more than a hundred models includingthose with register numbers: 3572, 3571, 3570, 3568, 3583, 4335 28233877, 3870, 3804, 4250, 5324, 5325, or the German Anton Meyers' modelsof pieces for assembling toys with model register numbers 4104, 4103,4102, 4093, 4092, 4091.

The pieces intended to be protected by the present invention have beenconceived with movement and gradable stability provided by its ownnature. Through a grooved-toothed system the final result can betransformable or it can have mobility. This transformable mobility iscarried on by manipulation and not by the effects of instability andcollapse of pieces. This characteristic is a different proposal from theprevious art because, by having movement through manipulation when thetoy is being constructed as well as at the final result, there are muchmore possibilities of creation and other options for toy constructions.

As it can be appreciated in FIG. 13, the thirteenth piece of the 3Dassembly toy is constituted by a tube with a 90 degree curve (45), withits two reduced ends (46), this reduction allowing theconnection-engagement to the pieces illustrated in FIGS. 1, 2, 14 and15. As it is illustrated in FIG. 14, the fourteenth piece of the 3Dassembly toy is constituted by a circular tube (47) where the piecesillustrated in FIGS. 5, 6, 7, 8, 9 and 13 are engaged with on theirinternal diameter and the pieces illustrated in FIGS. 1, 2, 3, 4, 5, 6,11 and 12 on their external diameter.

The 13 pieces illustrated in FIGS. 1 to 13 serve asconnections-connectors-fasteners, engaging the smaller diameter ends(49) into the larger diameter ends (50). The tubular semicircles (51)fasten the pieces and the circular, smooth or grooved, tubes ofdifferent lengths (52). All semicircles, smooth or toothed, can beopened and then closed because they are manufactured with flexiblematerial which also allows the free displacement all over the length ofthe circular tubes, smooth or grooved, and provides a 360 degree freerotation over all the external circumference of the pieces and circulartubes, on their external diameter; the grooved pieces (53), inconjunction with the toothed pieces (54) will bring gradation tostabilize the development and final results in creating figures. Therotation movement also is present when a smaller diameter (49)engages—gets into another of larger diameter (50. In the case of thewheel, the central circumference of the wheel (55) allows the piecesillustrated in FIGS. 1, 2, 14 and 15 to engage—get inside.
